Hi, I got a sub-class of a TreeStore (see below) and I want to cancel a
DND operation if it's not apropriate. But my RowDraggable method is
never called.. I'am missing something ?
public class MyTreeStore : TreeStore, TreeDragSource {
public MyTreeStore(params System.Type[] p) : base(p) {
}
bool TreeDragSource.RowDraggable(TreePath path){
Console.WriteLine("RowDraggable...");
return false;
}
}
I use it in a sub-class of a TreeView that goes like that :
public class MyTreeView : TreeView {
public MyTreeView(){
this.Reorderable = true;
this.AppendColumn ("Col1", new CellRendererText(), "text", 0);
this.AppendColumn ("Col2", new CellRendererText(), "text", 1);
this.Model = new MyTreeStore(
typeof(string),
typeof(string)
);
((MyTreeStore)this.Model).AppendValues(
"L1C1",
"L1C2"
);
((MyTreeStore)this.Model).AppendValues(
"L2C1",
"L2C2"
);
}
}
I known that there is some subtilities to override Interface methods in
sub-classes in C# but, as far as I know, my code take care of it..
Any tought ?
